The evaporator and condenser is isobaric with a net heat transfer 250 W in a vapor-compression refrigeration cycle. The cycle operates with R-134a working fluid at a steady state. The compressor's isentropic efficiency is at 60% with a high pressure of 16 bar and low pressure of 1 bar during the cycle. Solve for the mass flow rate, coefficient of performance, and draw the T-s diagram.
